Garage door opener rail is visibly bent or twisted, causing jerky movement.

Safety first: Disconnect power and secure the door in the closed position before working on the rail.

Steps to address:

• Assess damage: If the rail is slightly bent, minor straightening may be possible. Severe bends or kinks require rail replacement.
• Attempt gentle straightening: With the rail removed from the header and opener, carefully straighten using padded clamps or a vise. Avoid creating new kinks.
• Replace rail if needed: Order a Motorlift replacement rail assembly compatible with your model and install per manufacturer instructions.
• Check door hardware: Correct any underlying door issues (binding, weight) that may have caused the rail to bend.
